Following a border conflict that killed dozens of people and displaced hundreds of thousands more, Thailand and Cambodia agreed to an “immediate and unconditional ceasefire” on Monday, The Washington Post reported.

The ceasefire will begin at midnight local time, Malaysian Prime Minister Anwar Ibrahim, who helped mediate the ceasefire agreement, said at a press conference Monday.

As the conflict heightened last week, the U.S. State Department issued travel advisories for both Thailand and Cambodia. Here’s what to know about traveling to the countries right now, as well as the cause of the conflict and the ceasefire.

Why is there a travel advisory for Thailand and Cambodia?

The State Department issued travel advisories on Friday for both Thailand and Cambodia as conflict ramped up between the two nations.

Areas within 50 kilometers of the Cambodia-Thailand border are designated “Level 4: Do Not Travel” by the State Department.

“There are reports of fighting, including rocket and artillery fire, between Cambodian and Thai forces along the border,” according to the advisory. “Armed conflict has led to civilian casualties, and the Thai government has ordered the evacuation of certain areas.”

Outside of the border areas, the advisory levels for both countries were increased to “Level 2: Exercise Increased Caution” due to risk of “unrest.”

What started the Thailand-Cambodia conflict?

Although the fighting flared up last week, Thailand and Cambodia have a history of disputes over their shared border, according to The Associated Press, including conflicts over ownership of an ancient Hindu temple, Preah Vihear.

Tensions began rising in May of this year, when a Cambodian soldier was killed after Thai and Cambodian forces briefly fired at each other in a border area, per the AP.

Earlier this month, Thailand’s prime minister, Paetongtarn Shinawatra, was suspended by a Thai court due to comments she made in a phone call to Cambodian leader Hun Sen about the border, in which she appeared to disparage the Thai military, The New York Times reported.

But the conflict worsened last week after a mine explosion took place on the border, which killed five Thai soldiers.

Both countries have laid the blame on each other for the escalation, which began last Thursday, per the Times. Thailand claims Cambodia fired rockets into civilian areas, and Cambodia is accusing Thailand of firing first on Cambodian troops.

At least 35 people have been killed and over 260,000 people have been displaced from their homes during the latest conflict, according to the AP.

What to know about Thailand and Cambodia’s ceasefire

Cambodia and Thailand agreed to a ceasefire on Monday, after talks took place in Malaysia with representatives from China and the U.S. in attendance, The Washington Post reported.

According to the Post, Hun Manet said he hoped the talks would “stop immediately the fighting that have caused many lives lost, injuries, and also caused a lot of displacement of people.”

Phumtham said that President Donald Trump called to offer congratulations after the ceasefire was announced, per the AP. During the call, Phumtham thanked Trump for his “important role” in coming to an agreement.

On Saturday, Trump called both Phumtham and Hun Manet and threatened to stop negotiating trade deals over tariffs with the countries if the conflict didn’t end, according to the Times, and Secretary of State Marco Rubio also spoke with Thai and Cambodian officials over the weekend.

“The United States applauds the ceasefire declaration between Cambodia and Thailand announced today in Kuala Lumpur,” Rubio said in a statement on Monday. “President Trump and I are committed to an immediate cessation of violence and expect the governments of Cambodia and Thailand to fully honor their commitments to end this conflict.”
